Twist drill bits are the most versatile and widely used type of hole drill bit. They feature a spiral cutting edge that allows for easy drilling in a variety of materials. Twist drill bits come in various sizes and are suitable for general purpose drilling tasks.
There are different types of bits available for rock drilling, each designed for specific rock formations and drilling conditions. Some common types include roller cone bits, fixed cutter bits, and diamond core bits. Roller cone bits are typically used for softer formations, while fixed cutter bits are more suitable for harder rocks. Diamond core bits, on the other hand, are used for core sampling or drilling in extremely hard formations.
